Accessing window surface natively
Application events are essential to understand, but not very exciting. An interesting feature of the Android NDK is the ability to access the display window natively. With this privileged access, applications can draw any graphics they want onscreen.
We will now exploit this feature to get a graphic feedback in our application: a red square on screen. This square is going to represent the spaceship the user will control during the game.
Note
The resulting project is provided with this book under the name DroidBlaster_Part3.
